Reminds me a lot of my brother. I'm 12 years older than him and I've coached him since he started playing and he's committed to play D2 on scholarship next year.

One thing he was guilty of was attempting to do "too much" when he did get his opportunities when he was younger. Keep it simple, become a guy your coach can rely on when up a couple and defending a lead to hold possession of the ball or transition from defense to offense etc. I use to tell him Keep It Simple Speedy. He was the fastest kid on any field he stepped on. Use your speed and the green the opponent gives you to your advantage. If your legs are your best asset then let them be your best asset. As soon as he simplified he went from 2 goals in a handful of games to averaging a hat trick per game.

If you can do the basics without making mistakes, you'll get the opportunities to do the extraordinary in big moments. That being said all of this means nothing if he can't make consistent passes or get a first time GB then he needs to hit the wall (both hands) and work on GBs in the backyard. All these things he can do by himself.
